In a recent study published in the journal Nature Human Behaviour, researchers used a large, binational cohort (total n = 4,731,778) to investigate the short- and long-term associations between SARS-CoV-2 infections and subsequent adverse neuropsychiatric outcomes. They used exposure-driven propensity score matching to compare their samples’ outcomes against the general population and individuals with a non-SARS-CoV-2 respiratory infection.
